[BUG/APPEAL] Lost my enchantment

A while ago, I acquired a Fortune III Efficiency IV pick.
I used it for quite a while, and occasionally shoved it into my pipe distribution system, only to find it in the appropiate chest later when I needed it.

Right after Tekkit had an update I did the same: tossed my pick into the distribution system.
Only this time, when I opened the chest, there it was, without its enchantment. It had about half its HP when it happened.

I've stopped mining ever since, but I would still like it back, or to be compensated for losing it.
Psycix is witness to this.
